Using your Gochizo set is super easy. First, locate the new switch on the units to toggle between Shouma and Gochizo modes. To enjoy the auto - chat mode, just let the units do their thing and hear random Gochizo voices. If you have the DX Henshin Belt Gavv, simply connect the Gochizo to it for more fun. As for maintenance, keep the units dry and away from direct sunlight. Avoid dropping them as it might damage the voice unit. If you encounter any issues, contact our customer service. Have a great time with your Gochizo set!
